Charter Environmental, a construction company working on the Muddy River Project, will be conducting Statnamic testing at Brookline Avenue at the old Sears building rotary.

The testing consists of extremely loud blasts into the ground to test the strength of existing pilings and support structures located underground. The tests are said to sound like cannon blasts or very loud gunshots.

The loud sounds will last approximately one second each time.

Police said if residents or visitors hear anything that they don’t think is related to the blasts, they should call 911.

The initial tests were scheduled for Tuesday morning, but the project coordinator said one of the trucks delivering the equipment from Florida broke down and will be late in arriving to the project site.

The first test will be conducted Wednesday afternoon between 1 p.m. and 3 p.m.
